Tapered connectors are purpose-built elements used to unite pipes of varying diameters in drainage networks. Their role is to ensure a streamlined size reduction, which helps prevent flow restriction, backflow, or leakage. When drainage systems are modified, tapers deliver a more secure solution than forcing mismatched pipes together.
Taper Bends: Redirection and Size Change in One
Tapered elbow fittings combine a shift in pipe direction with a simultaneous pipe size transition. These fittings are most common in angles such as 11°, 22.5°, 45°, or 90°, and they’re particularly effective in installations where space is restricted or multiple transitions are needed. They cut down on the number of individual components, helping to lower failure points in the system.
Where Tapers and Bends Are Commonly Used
These fittings are widely installed across various drainage applications:
- In pump chambers, to join large outflow pipes to smaller distribution lines
- Throughout retrofit projects with updated or non-standardised pipework
- Across field drainage systems where flow rates and gradients must be kept steady
- Inside wastewater facilities where components need to be space-saving and multi-functional
Correctly applied, these fittings optimise flow, reduce energy loss from turbulence, and help meet compliance benchmarks for water management.
Why Size Precision Matters
Incorrectly sized joints can cause:
- Disturbances in hydraulic pressure
- Blockages from sedimentation
- Accelerated joint degradation
Tapers and taper bends create an even flow path by offering a controlled reduction, improving flow performance and reducing long-term maintenance.
Why Choosing the Right Supplier Makes a Difference
Choosing a general merchant might offer convenience, but a specialist drainage supplier brings:
- Greater range of product sizes and angles
- Better material suitability
- Industry-specific expertise
- Components meeting required standards
A dedicated supplier will have fittings that are not only dimensionally correct but also proven in field conditions—ensuring long-term system integrity.
FAQs
Is a taper the same as a reducer?
No. Tapers feature a longer and more gradual size change, which is more effective for systems needing steady flow. Reducers often reduce quickly, which may impact flow stability.
Can taper bends be used underground?
Yes, provided they are made from suitable materials and follow relevant local guidelines.
Are tapers compatible with clay and plastic pipes?
Tapers are usually manufactured for one pipe type, but adaptors can bridge the gap between clay, plastic, and other pipe materials.
Do taper bends reduce flow performance?
If properly integrated into the system, taper bends maintain consistent flow and can even improve it by reducing pressure drops.
What size taper should I choose?
Base your choice on pipe diameter and system flow requirements to select the correct taper size for the application.
Choose Smart, Fit Once
Whether you're replacing a few components or building a click here new network, fitting the correct tapers and taper bends is central to a low-maintenance and durable drainage setup.
